Stop Paying Twice: Find Long-Term Roamers Still on U.S. Mobile Plans

Many employees who've relocated abroad but kept U.S. lines (Verizon, AT&T, T-Mobile) create quiet double spend: plan MRC + international/roaming passes. Flag persistent roamers, confirm status, then move them to local service and park the U.S. number.

What to look for (fast signals)

• Repeated pass/roam activity for 60-90 days.

• One dominant country in usage/roam records.

• Roaming most days in a cycle (practically living abroad). My take: 15+ roaming/pass days in a month for 2+ months ≈ action.

Carrier notes (just enough detail)

• Verizon: TravelPass often shows the country. Easy to spot single-country patterns.

• AT&T & T-Mobile: International Day Pass appears as daily charges; usage detail shows roam country/network.

What to do

• Confirm with manager/HR (relocation vs. extended travel).

• Right-size:

  • Switch to local SIM/eSIM in-country.

  • Park/port the U.S. number to a low-cost tier/VoIP with call-forwarding.

  • Keep passes only for short, documented travel.

• Close loop: Update inventory/MDM; note exceptions.

Why it's worth it

• Example: $60 MRC + $10/day x 20 days ≈ $260/mo → local plan $25 + number park $5 ≈ $30/mo. Savings ≈ $230/mo/line (~$2.7K/yr). Multiply by flagged lines.

Light-touch governance

• Define "long-term roaming" (e.g., > 30 days in any 45).

• Require declaration of moves or trips > 30 days.

• Run a monthly sweep; resolve within two weeks.

Quick start

• Pull last 90 days of invoices/usage.

• Filter for international passes/roaming across Verizon, AT&T, T-Mobile.

• Prioritize top spenders; fix the first 10-20 lines for immediate savings.

Bottom line: A monthly sweep + quick confirmation + local eSIM turns waste into guaranteed savings without hurting user experience.
